    A torsion damping assembly, e.g. for a clutch disc, comprises two coaxial parts mounted for relative angular displacement within a predetermined range against the action of circumferentially acting resilient means. One of the coaxial parts comprises a transverse hub flange and the other of the coaxial parts comprises two transverse annular guide members or washers disposed on the respective sides of and spaced axially from the hub flange. The guide members are connected to each other by spaced axial connecting members. At least one strap member also interconnects the annular guide members, a first end of the strap member being fixed at one of the guide members, and a second end of the strap member circumferentially spaced from the first end being fixed to the other of the guide members. The strap member is secured to the other annular guide member by a fastening portion which is circumferentially offset relative to the attachment portion so that the strap member defines bracing for the axial connecting member.
