Zusammenfassung:A torque converter having a lockup clutch or a coupling device, for selectively providing a mechanical connection between a drive unit and a drive train. The lockup clutch (C) or coupling device has a driving part connected to the drive unit and a driven part connected to the drive train. The torque converter also has a control system for applying a first pressure in a sense to cause frictional engagement between the driving part and the driven part and a second pressure in a sense to cause disengagement of the driving part and the driven part. A differential between the pressures is progressively controllable by the control system so as to control the relative positioning between the driven part and the driving part.
