Abstract

An actuating device for applying actuating forces in a friction clutch device for engaging and disengaging a friction clutch assembly of the friction clutch device. The torque transmission device comprises the actuating device for transmission of torque between a drive unit and a transmission which also includes the friction clutch device. A method for installing a torque transmission device of this type. Various aspects relate to setting of a pre-load on a bearing of the actuating device, setting an over-dead-point configuration for a compensation spring associated with at least one rotary member of the actuating device, setting a rotation movement range for the rotary member and/or an axial movement range for an actuating element which can be displaced axially by rotation movement imparted to the rotary member, and producing either a normally engaged or disengaged characteristic in a normally-engaged or normally-disengaged friction clutch assembly with the compensation spring.
