1. An actuating device for actuating a shifting element, wherein the actuating device and shifting element are for mounting on a rotating shaft in a vehicle transmission, the actuating device comprising:
- a shifting device operably configured with the shifting element;
the shifting device comprising a pressure space for receipt of a pressurized medium;
an electrically controlled shut-off valve disposed so as to maintain pressure in the pressure space of the shifting device; and
wherein the shut-off valve is configured with the shifting device so as to be supplied with electrical energy in a contact-free manner without electrical transmission lines to the shut-off valve.

Abstract
An actuating device is provided for actuating at least one shifting element shiftable through a shifting device, whereas the shifting device features a pressure space with a supply for a pressurized medium, along with a shut-off valve. It is proposed that the shut-off valve is connected in an electrically controllable and torque-proof manner to at least one shifting element, and that the electrical energy for the actuation of the shut-off valve is able to be supplied without contact.
