The present invention is directed to a prosthetic adapter that allows for rotation of a prosthetic about central axis. In one embodiment, the invention is a prosthetic adapter comprising: a first component adapted to be coupled to a residual limb; a second component adapted to be coupled to a prosthesis; the first component or the second component comprising a collar forming a central cavity formed about a first central axis; the other one of the first component or the second component comprising a hub extending along a second central axis, the hub positioned in the central cavity so that the first and second central axes are substantially coaxial; wherein when the hub is positioned within the central cavity of the collar, the hub has only two degrees of freedom, rotation about the first central axis and translation along the first central axis.
