The invention relates to a torque transmission device that is to be arranged in a drive train of a hybrid vehicle having an internal combustion engine, a transmission and an electric machine, the electric machine being arranged in the torque transmission device. The torque transmission device includes a disconnect clutch with clutch actuation, for decoupling the internal combustion engine from the transmission, and a primary torsional vibration damper on the crankshaft side. The invention has a secondary torsional vibration damper arranged on the transmission side, radially and axially inside the rotor and directly on the transmission-side output flange of the torque transmission device. This allows the installation space for the crankshaft-side primary torsional vibration damper to be increased, such that the damper can be optimally designed. In torque transmission devices which originally have no secondary damper, the design of the primary damper can be smaller and more compact since the secondary damper supports the vibration damping. Since the secondary damper is arranged inside the rotor of the electric machine and directly on the transmission-side output flange of the torque transmission device, this damper requires only minimal or no additional installation space. This leaves surplus installation space which can be used, for example, to reduce the size of the torque transmission device, in particular to axially shorten it, or be used to increase the size of the electric machine.
