Abstract
A rotary transmission apparatus () for the transmission of control and/or working pressures to a fluid duet () which is received or configured at least in regions in the interior of a shaft (), in particular, a drive shaft. The rotary transmission apparatus () has a stator assembly () which is arranged in a stationary manner with respect to a rotational movement of the shaft () and has at least one fluid feed/discharge line () and a control element () which can be displaced in the shaft longitudinal direction (L) relative to the shaft () between a first position and a second position. A flow connection between the at least one fluid feed/discharge line () and the fluid duct () is interrupted in the first position of the control element (), and a flow connection between the at least one fluid feed/discharge line () and the fluid duct () is established in the second position of the control element ().
