The adapter of claim 9, further comprising: a retaining ring, wherein the radially outwardly facing surfaces of each of the shoulder pieces define a planar supporting surface extending from the radially outwardly facing surfaces to a radially inwardly facing surface at the opening cross section of the collar element such that the planar supporting surface provides a mounting surface for the retaining ring, and the retaining ring is formed such that the adapter top is capable of being secured to the adapter bottom by mounting the retaining ring on the first shoulder piece and the second shoulder piece. 11. The adapter of claim 10, wherein the retaining ring is made of a metal. 12. The adapter of claim 10, wherein each of the shoulder pieces includes at least one blind hole and each of the at least one blind holes has a position aligned with a position of a corresponding hole in the retaining ring, such that the retaining ring rests against an upper supporting surface of the two shoulder pieces. 13. The adapter of claim 1, wherein the attachment flange includes a flange disc, and a flange face of the flange disc of the attachment flange is larger than a joining surface, formed to the flange disc, of the collar element. 14. The adapter of claim 1, wherein the attachment flange comprises a plurality of flange boreholes, arranged at a constant distance from a central point such that the plurality of flange boreholes are capable of providing a detachable fixed connection of the attachment flange to the floor by using screws, the central point coinciding with a center of the central flange opening, and the constant distance being larger than a radius of the central flange opening. 15.
