Abstract
A friction clutch wherein a first unit including the cover, the diaphragm spring and the pressure plate is separably connected to a second unit including the clutch plate and its linings by a coupling device which centers the clutch plate relative to the pressure plate and maintains the clutch plate at an optimum distance from the cover for attachment of the cover to the flywheel on the crankshaft of the engine in a motor vehicle wherein the clutch plate is to transmit torque to the input shaft of a variable-speed transmission when the clutch is engaged. The coupling device is deactivated or destroyed in response to attachment of the cover to the flywheel.
