An adjustment device (1) for a friction clutch (2), including at least the following components: a rotatable driving device (3); an adjustment spindle (4) having an axial direction, which is connected to the driving device in a rotationally fixed manner; a spindle nut (6), which is moved in the axial direction by rotation of the adjustment spindle; and an adjusting unit (7) for adjusting a distance (8) between an engagement device (9) and a pressure plate (10), which adjusting unit is adjusted by an axial motion of the spindle nut (6) in such a way that the axial direction (5) of the adjustment spindle (4) can be oriented parallel to a radial direction (11) of the friction clutch (2). Through the adjustment device here, it is possible to realize a robust functional unit that is sufficiently stiff with respect to the applied centrifugal forces and that has low production requirements, low weight, and low installation space.
