A friction clutch driven plate having a friction facing carrier (14) mounted on a hub (11) with torsion damping springs (15, 48) operating in two stages to resist rotation of the carrier (14) around the hub (11). A friction damper (52, 42) operates during the initial damping phase together with first stage torsion damping springs (48). The friction damper comprises a flange plate (43) rotationally fast with the hub(11), a pair of side plates (41, 42) fast with the carrier (14) and located on each side of the flange plate (43), and a friction plate (52) located between the flange plate (43) and one of the side plates (42). The friction plate (52) is free to rotate relative to the other plates (41, 42, 43) and is biased into frictional engagement with the side plate (42) to generate the friction damping. The plates (41, 42, 43) also house the springs (48) and form part of the first stage torsion damping means.
