A device includes a torque-proof first structural component and a second structural component rotatably connected to the first component. Hydraulic fluid is guided to lubrication points via the components. A sealing device seals an interface between the components. The interface includes a transition area limited by areas of the components that overlap in the radial direction and which carries hydraulic fluid, and which is connected to supply areas for hydraulic fluid of the first component and transmission areas for hydraulic fluid of the second component. The hydraulic fluid forms a floating hydrodynamic bearing between the components. The sealing device includes at least one thread area in the area of a surface of the second component or of the first component that is facing towards the surface of the first component or the second component.
