1. A torque-transmitting device, comprising:
a first input side, a second input side, an output side, a hydrodynamic converter, a lock-up clutch, a first torque-transmitting path which runs between a splitting point and a merging point, and a second torque-transmitting path which is configured so as to be parallel with respect to the first torque-transmitting path;
wherein the hydrodynamic converter is arranged in the first torque-transmitting path and the lock-up clutch is arranged in the second torque-transmitting path;
wherein the hydrodynamic converter has a pump wheel and a turbine wheel which is hydrodynamically connectable to the pump wheel;
wherein the splitting point is connected to the first input side for conjoint rotation;
wherein the pump wheel and a first clutch input side of the lock-up clutch are each connected to the splitting point for conjoint rotation;
wherein a second input side is connected downstream of the merging point in a torque flow of a first torque from the first input side to the output side.
