1. A friction clutch for mounting to a flywheel in a motor vehicle, said friction clutch comprising: a clutch housing which can be fixed to said flywheel; a pressure plate mounted essentially non-rotatably but with freedom of axial movement with respect to said housing; a plurality of spacer bolts which project axially from the clutch housing and having free ends distal to said housing; a diaphragm spring which acts as a pressure spring to urge said pressure plate toward said flywheel, said diaphragm spring having openings through which said spacer bolts pass, said diaphragm spring being mounted on said spacer bolts so that said diaphragm spring can tilt with respect to said housing; and a friction damping device comprising a plurality of radially pretensioned friction springs installed between the pressure plate and a component with respect to which the pressure plate can move axially, wherein the friction springs are attached to the free ends of the spacer bolts.
