1. A torque transmission apparatus for transmitting a torque between a first drive element and an output element, comprising:
a torque converter having a torque converter input, which is rotatable about a rotation axis (A) and is coupled to the first drive element, and a torque converter output, which can be connected to the output element,
a separating clutch arranged outside of the torque converter and effectively arranged between the first drive element and the torque converter, having a clutch input and a clutch output, which is selectively connected thereto by an action of a clutch actuating apparatus, wherein
the clutch actuating apparatus has a pressure medium chamber and a pressure medium channel (K4) supplying said pressure medium chamber with pressure medium,
the separating clutch is dry-operated and the pressure medium channel (K4) extends through the torque converter at least in portions, and
the pressure medium channel (K4) comprises a first through opening in the torque converter input.
