Abstract
A torsion device comprising an input part (20) comprising a piston (24) equipped with a guide washer (28) and an output part comprising an annular disc (36), and of the type comprising a series of lugs (44) folded radially inwards and which cooperate with the section (42) of a peripheral edge (40) of the disc (36). The edge (40) comprises a series of slots (48) distributed angularly like the lugs (44) of the first portion and dimensioned so as to allow the axial introduction of the lugs (44) into the slots (48) then the axial retention of the second portion (22) inside the first portion (20) by the relative rotation of these two portions by a fraction of a turn, in the manner of a bayonet-type mounting.
