1. A torque transmitting device for transmitting a torque between a first drive element and an output element, the torque transmitting device comprising:
a torque transmitting unit having a housing for delimiting a first fluid chamber that is finable with a liquid, an input which is rotatable about an axis of rotation that is couplable to the first drive element and an output which is connectable to the output element;
a separating clutch arranged outside of the torque transmitting unit and the first fluid chamber in a second fluid chamber separated in a fluid-tight manner and configured for selectable torque transmission between the first drive element and the torque transmitting unit, the separating clutch including a clutch input and a clutch output that is connectable therewith via a friction device and a clutch actuation device;
the clutch actuation device comprises a pressing element and an actuation element which is connected thereto, to which fluid pressure is appliable and is movable thereby, the actuation element and the pressing element are arranged to be axially spaced apart and non-overlapping, and radially overlapping one another;
the pressing element transmits an actuation force of the actuation element to the friction device to bring about a frictional connection between the clutch input and the clutch output, wherein the actuation element is connected to the pressing element via a transmission element which is movable via the movement of the actuation element, and the transmission element movably moves through the housing; and
the pressing element is arranged outside of the first fluid chamber and within the second fluid chamber and the actuation element is at least partly arranged within the first fluid chamber so that pressure is applied thereto by the fluid pressure.
