12. A wind turbine, comprising:
a planetary transmission comprising a first transmission part comprising a bush arranged such as to rest in a rotationally fixed manner on a rest of the first transmission part and comprising sealing grooves, a second transmission part, said bush of the first transmission part pointing toward the second transmission part for transferring a supply medium, a transfer device designed to transfer the supply medium between the first transmission part and the second transmission part, with the first and second transmission part each at least partially forming a part of the transfer device and with the first transmission part and the second transmission part exhibiting a rotational movement relative to one another during operation of the planetary transmission, said transfer device comprising an annular groove on a surface of the first transmission part or on a surface of the second transmission part, and bores distributed around a periphery such that the bores are arranged opposite the annular groove, with the sealing grooves formed in the bush axially on both sides of the annular groove, and sealing rings respectively arranged in the sealing grooves, wherein the bush is configured in floating form in an axial direction with a sufficient amount of play to tilt out of a relative position which is coaxial with the first transmission part and/or with the second transmission part to the extent of a relative movability of a respective one of the sealing rings within an associated one of the sealing grooves; or
a drive train comprising an electric machine with a rotor, and the planetary transmission, with the planetary transmission comprising a shaft, said rotor of the electric machine being connected to the shaft of the planetary transmission in a force-fitting and/or form fitting manner.
