A temperature-controlled fluid friction coupling is actuated by a flow of viscous fluid flowing into or out of shearing surface gaps disposed therein. An, the actuating pin is movable in a direction parallel to a surface of a partition. A swing-type valve lever is in contact with the actuating pin near a root end of the valve lever, and a swing end of the valve lever is arranged slidably movable while in contact with a surface of the partition having a valve opening therein. In response to a deformation of the temperature sensitive element caused by a change of air temperature, the actuating pin moves in a direction parallel to the surface of the partition, and then the swing end of the valve lever moves so as to open and close the valve opening. Thus, the fluid flow from a reservoir chamber to a torque transmitting chamber is controlled.
