1. A transmission device (1) having at least one sleeve shifting element (11) being actuated by an actuator device (4) having at least one electric actuator component (5, 17), characterized in that the at least one electric actuator component (5, 17) being rotationally fixed to a countershaft (3) of the transmission and being functionally connected, via a rotary transformer (15), with additional components of the transmission device (1) that are rigidly secured to a transmission housing, the rotary transformer (15) transmitting at least one of electrical energy and electrical data, by one of an inductive or a capacitive coupling, between the additional components of the transmission device (1) and the at least one of the electric component (5, 17).
2. The transmission device as claimed in claim 1, wherein a first coil element (15A) of the rotary transformer (15) is fixed within the countershaft (3).
3. The transmission device as claimed in claim 2, wherein a second coil element (15B) of the rotary transformer (15) is rigidly secured outside of the countershaft (3).
4. The transmission device as claimed in claim 1, wherein the rotary transformer (15) transmits electrical energy and electrical data within a range of frequencies.
5. The transmission device as claimed in claim 2, wherein the first coil element (15A) of the rotary transformer (15) and the electric actuator component (5, 17) are combined with one another in a common module.
6. The transmission device according to claim 3, wherein the second coil element (15B) of the rotary transformer (15) and at least one of a transmission control device and at least one connector of the transmission are combined with one another in a common module.
