1. A drive device, comprising:
an internal combustion engine connection which is configured for receiving drive power from an internal combustion engine;
an electric motor generator connection which is configured for receiving drive power from an electric motor generator;
a coupling device that couples both the internal combustion engine connection and the electric motor generator connection to at least one power train connection which delivers drive power to a power train,
wherein the coupling device has a radially outer drive part and a coupling portion which lies radially inside the drive part and is configured for selectively connecting the drive part to the at least one power train connection in a rotationally fixed fashion,
wherein a power transmission portion is arranged on an outer circumferential surface on the radially outer drive part and is configured for receiving drive power from the electric motor generator,
wherein both the internal combustion engine connection and the electric motor generator connection are arranged concentrically to a main drive axis,
wherein the power transmission portion at least partially or completely covers the coupling portion in a longitudinal direction of the main drive axis,
wherein an electric motor axis, about which an electric motor shaft rotates which is configured for delivering drive power from the electric motor generator, is arranged axially parallel to and radially spaced from the main drive axis,
wherein the coupling device is a dual clutch and has a radially outer first partial clutch and a second partial clutch arranged radially inside the first partial clutch,
wherein the first partial clutch is configured for selectively connecting the drive part to said power train connection in a rotationally fixed fashion, and
wherein the second partial clutch is configured for selectively connecting the drive part to a further power train connection in a rotationally fixed fashion.
