A device for pressing a double clutch (130) onto a transmission shaft arranged in a clutch housing (127) of a gearbox. The device is used for different embodiments of the clutch housing (127) of the double clutch transmission. The device includes a plurality of tie bolts (126, 126/1), stationarily connectable to the clutch housing (127), a pressing device (100), which is provided with an axially adjustable pressing rod (101) and can be brought into pressing connection with the double clutch (130) and a support device (1) connecting the tie bolts (126, 126/1) to the pressing rod. The support device (1) has a central mounting element (2, 3, 4), in which the pressing device (100) is mounted. The support device (1) has a plurality of support arms (5, 6, 7), which each mesh with one of the tie bolts (126, 126/1). The support arms (5, 6, 7) are mounted at the mounting element (2, 3, 4) about a pivot axis in parallel to the pressing rod (101) for the alignment of the pressing device (100) with the transmission shaft.
