Abstract of the Disclosure A clutch and damper assembly wherein a single plate clutch has torsion springs and deformable resilient members permitting a wide angle of travel, disposed between the clutch input and output to accommodate engine torsional vibrations imposed on the clutch. The torsion springs permit a predetermined amount of relative angular movement between the clutch input and output at a predetermined rate and the resilient, members become operable after the predetermined motion to permit further relative motion at a higher rate. A friction assembly included within the damper dissipates the periodic energy of the torsional vibrations.
