The invention relates to a drive device (1) for a hybrid powertrain of a motor vehicle comprising an internal combustion engine and an electric machine (4) arranged coaxially to the internal combustion engine. A torsional vibration damper (9) is arranged between a rotor (6) of the electric machine (4) and an output shaft (8) of the drive device (1), said torsional vibration damper comprising a spring device (10) which is arranged between the rotor (6) and the output shaft (8) so as to act in the circumferential direction. The aim of the invention is to provide an improved torsional vibration damping of the drive device (1) in a partial load range of the internal combustion engine while taking into consideration the mass moment of inertia of the rotor (6). This is achieved in that the torsion spring rate of the spring device (10) is less than or equal to 20 Nm/°, preferably less than or equal to 10 Nm/°, particularly preferably less than or equal to 5 Nm/°, in a specified rotational angle range between the rotor (6) and the output shaft (8), said rotational angle range being less than a maximum rotational angle.
