1. A drive device, in particular for an adjustable vehicle flap, comprising
a housing, wherein the housing extends axially along a drive axle,
a motor for generating a driving force in a direction of the drive axle,
a first drive element,
a coupling device arranged between the motor and the first drive element, wherein the coupling device comprises a coupling housing consisting of a laser-transparent plastic and at least one first coupling part with a coupling section for coupling to the first drive element, wherein the first drive element is coupled to the coupling device via the coupling section of the first coupling part, wherein the coupling section is designed as a hollow-cylindrical extension of the first coupling part, and
a braking device for braking a drive movement of the first drive element,
wherein the braking device is arranged axially completely in the coupling section of the first coupling part,
wherein a cover element is arranged at an open end of the coupling housing, wherein the cover element is designed as a stop part for the braking device, which is delimited on one side in the direction of the drive axle by the cover element, wherein the cover element is designed as an injection-molded part made from a plastic that is non-transparent to laser and has a smaller outer diameter than the hollow-cylindrical coupling housing, wherein the cover element is inserted into the open end of the coupling housing and is fixed to the coupling housing by laser welding.
