The invention relates to a clutch for the controllable transmission of a torque, comprising a first and a second clutch element, notably a shaft (11) and a clutch housing (12), which are mounted such that they can rotate in relation to each other. The clutch comprises a friction coupling (15) and a viscous coupling (14) which are connected in parallel. The friction coupling comprises two friction disk sets and the viscous coupling two viscous disk sets which are each assigned to one of two viscous disk supports. The friction disk sets of the friction coupling are each non-rotationally fixed to the first and second coupling element and subjected to the axial action of an adjustment device (13). A first viscous disk support of the viscous coupling is permanently connected to the first of the coupling elements in a non-rotating manner and a second viscous disk support of the viscous coupling is connected to the second coupling member such that it can be disengaged. An axial adjustment device frictionally engages and disengages the second viscous disk support of the viscous coupling and closes and releases the friction disk sets of the friction coupling.
