Abstract
A torsion damping device of the kind comprising two rotatable parts with coil springs interposed between them. At least one friction pad is associated with each spring so as to come into engagement with a contact zone of one of the said coaxial parts. In accordance with the invention, there is associated with each of the friction pads an intermediate resilient member which is radially deformable and which has a first engagement zone for engagement with a turn of the spring, together with a second engagement zone for contact with the friction pad, the intermediate resilient member being interposed radially between the friction pad and the spring.
