A hydrokinetic torque converter, particularly for use in the power train of a motor vehicle, has a housing which can receive torque from the prime mover of the vehicle and drives a pump adapted to rotate a turbine on the input shaft of the change-speed transmission. The turbine can also receive torque from the housing by way of a bypass clutch and a damper borne by a hub which is mounted on the input shaft. A feature of the invention resides in the simplicity of design and low cost of several component parts of the torque converter and in a novel mode of assembling the component parts.
