A fluid coupling device is provided of the type including an input coupling (11) and an output coupling assembly (13) including a case cover member (17) including a chimney portion (39) and chimney extension (81). The coupling includes a valve plate (31) defining a fluid port (45), and operation of the coupling is controlled in response to the rotational position of the valve arm (43), by means of a valve shaft (41). The position of the valve shaft (41) is controlled, in response to an electrical input signal by means of an actuator assembly (61), which includes an annular steel housing member (63). The housing member is stationary, and is mounted relative to the chimney extension (81) by means of a set of ball bearings (77) which comprise the only bearing support between the actuator assembly (61) and the rotating coupling. |
