That's false.
Mar_3:29 But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation:
damnation:
G2920
κρίσις
krisis
kree'-sis
(Subjectively or objectively, for or against); by extension a tribunal; by implication justice (specifically divine law): - accusation, condemnation, damnation, judgment.
Total KJV occurrences: 48
Eternal damnation is another way to say eternal judgment which is a decision made by a court or Judge etc. It does not mean torment or torture. To understand what punishment was decided all we have to do is find out what the judgment is for the unsaved:
Rev_20:13 And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works.
Rev_20:14 And death and hell were cast into the lake of fire. This is the second death.
The second death is the eternal judgment making it an eternal death. Eternal torment doctrine teaches the opposite so the unsaved are eternally alive and being tortured when the scripture say the unsaved will be dead for all eternity.
The way you are using strong's is a word study fallacy.

Cognate: 2851 kólasis (from kolaphos, "a buffeting, a blow") – properly, punishment that "fits" (matches) the one punished (R. Trench);
torment from living in the dread of upcoming judgment from shirking one's duty (cf. WS at 1 Jn 4:18).
Perfected love casts out tormenting fear (2851 /kólasis)
1 Jn 4:17,18: "17By this, love is perfected [brought to its higher stages] with us, so that we may continuously have confidence in the day of judgment; because as He is, so also are we in this world. 18There is no fear in love; but perfect love casts out fear, because fear involves punishment [2851 /kólasis,
"torment"], and the one who fears is not perfected in love."

STRONGS NT 2851: κόλασις
κόλασις, κολάσεως, ἡ (κολάζω), correction, punishment, penalty: Matthew 25:46; κόλασιν ἔχει,brings with it or has connected with it the
thought of punishment, 1 John 4:18. (Ezekiel 14:3f, etc.; 2 Macc. 4:38; 4 Macc. 8:8; Wis. 11:14 Wis. 16:24, etc.; Plato, Aristotle, Diodorus 1, 77 (9); 4, 44 (3); Aelian v. h. 7, 15; others.) [SYNONYMS: κόλασις, τιμωρία: the noted definition of Aristotle, which distinguishes κόλασις from τιμωρία as that which (is disciplinary and) has reference
to him who suffers, while the latter (is penal and) has reference to the satisfaction of him who inflicts, may be found in his rhet. 1, 10, 17; cf. Cope, Introduction to Aristotle, Rhet., p. 232. To much the same effect, Plato, Protag. 324 a. and following, also deff. 416. But, as in other cases, usage (especially the later) does not always recognize the distinction; see e. g. Philo de legat. ad Gaium § 1 at the end; fragment ex Eusebius prepos. evang. 8, 13 (Mang. 2:641); de vita Moys. 1:16 at the end; Plato de sera num. vind. §§ 9, 11, etc. Plutarch (ibid. § 25 under the end) uses κολάζομαι of those undergoing the penalties of the other world (cf. Justin Martyr, Apology 1, 8; Clement of Rome, 2 Cor. 6, 7 [ET]; Justin Martyr, Apology 1, 43; 2, 8; Test xii. Patr., test. Reub. 5; test. Levi 4, etc.; Martyr. Polycarp, 2, 3 [ET]; 11, 2 [ET]; Ignatius ad Rom. 5, 3 [ET]; Martyr Ignatius vat. 5 etc.). See Trench, Synonyms, § vii.; McClellan, New Testament, vol. i., margin references on Matt. as above; Bartlett, Life and Death Eternal. Note G.; C. F. Hudson, Debt and Grace, p. 188ff; Schmidt, chapter 167, 2f.]
