In a fluid friction clutch, the circulation of shearing fluid is controlled by a control of the return flow of the shearing fluid from a clutch working chamber into a clutch storage chamber. The return flow is controlled by a control piston which is movable axially of the clutch to selectively block and open a radially extending return flow duct. In certain embodiments the control piston also controls an inflow bore.
