Assembly device and method for assembling a shaft-cover module

The invention relates to an assembly device for assembling a shaft-cover module (400), which comprises a cover (104) and at least one function shaft having a plurality of functional elements (100, 112) that are fixed to a shaft (114) rotatably mounted in the cover (104). The assembly device comprises a plurality of positioning elements (18, 22) arranged axially spaced for receiving in alignment each functional element (100, 112) provided with a central aperture (102, 113), such that in the aligned state the functional elements (100, 112) assume a predetermined azimuthal angular position with respect to each other and the central apertures (102, 113) thereof align with each other; a cover support, by means of which the cylinder head cover (104) having at least two wall apertures (106, 108) can be held oriented in such a way that the wall apertures (106, 108) thereof align with the central apertures (102, 113) of the aligned functional elements (100, 112); a dummy shaft support (14), by means of which a dummy s
