1. A torque transmission device for transmitting a torque between a first drive element and an output element, the torque transmission device comprising:
a torque transmission unit which has a housing having at least one housing wall for delimiting a first fluid chamber which is fillable with a liquid;
an input, which is rotatable about a rotation axis and configured to be coupled to the first drive element, an output, which can configured to be connected to the output element, and a separating clutch, which is arranged outside of the torque transmission unit and the first fluid chamber in a second fluid chamber that is separated therefrom in a fluid-tight manner, and which is configured for selective torque transmission between the first drive element and the torque transmission unit, which separating clutch has a clutch input and a clutch output that is selectively connectable thereto via a clutch actuating device having an actuating element, wherein an actuating force acting on the actuating element within the housing is transmittable via a transmission element extending through the housing to the separating clutch as a tractive force for closing the separating clutch.
