A temperature-controlled, fluid-friction clutch filled with a viscous fluid. The clutch has a drive disk mounted for rotation, the disk being flexible in the direction of the rotational axis. First and second clutch-driven plates have respective co-planar drive surfaces facing and spaced apart from surfaces of the drive disk, the space between the clutch-driven plates defining a fluid working space. A fluid storage space is also defined and an element is provided for pumping fluid from the working space into the storage space. A temperature-controlled valve controls flow of fluid between the working space and the storage space.
