An electric actuator for controlling the output of a hydraulic drive device such as a transaxle or pump, including an adaptor to permit use of the actuator with multiple drive device designs without the need to modify the control shaft of the drive device. The actuator may include an offset arm disposed on a distal end of an output shaft, and a protrusion extending from the offset arm and offset from the axis of rotation of the control shaft of the drive device. A control arm is disposed on an end of the control shaft and includes a first opening to engage the control shaft and a second opening to receive the protrusion to enable the protrusion to cause rotation of the control arm.

A rotor assembly includes a torque converter having a housing forming a hydraulic chamber, a rotor for an electric motor, a rotor carrier non-rotatably connected to the rotor, wherein the rotor carrier is fixed to the torque converter housing, and a seal is disposed between the torque converter housing and rotor carrier for sealing therebetween. In some example embodiments, the rotor assembly has at least one bolt for fixing the torque converter housing to the rotor carrier. In some embodiments, the rotor carrier includes an aperture and the at least one bolt is disposed in the aperture.

A torque converter includes a front cover, an impeller, an output shaft member, a turbine and a clutch. The turbine includes a turbine shell, a turbine blade, a coupling portion and a piston portion. The turbine shell is supported by the output shaft member. Additionally, the turbine shell slides on the output shaft member in an axial direction. The turbine blade is attached to the turbine shell. The coupling portion extends from the turbine shell toward the front cover. The piston portion extends from the coupling portion in a radial direction. The clutch is disposed between the piston portion and the front cover.

Provided is a fluid fan clutch with excellent cooling performance capable of effectively preventing, by very simple means, a decrease in the volume of air due to backflow of cooling fan air occurring when the fan clutch is activated. The fluid fan clutch has a structure with a fan removably fixed to a housing composed of a front-side housing component (cover) and a back-side housing component (case), wherein projecting parts for preventing backflow of fan air are arranged on the back-side housing component so as to be shifted in the circumferential direction with respect to fixing projections of the front-side housing component.
