Abstract: A rotationally limited connection system that includes a first mount to hold an object or couple with an object, a first ferromagnetic coupling element that includes a material attracted to a magnet or wherein the material includes the magnet, an a first mechanical coupling element. The first mechanical coupling element includes at least one protrusion to limit rotation of the first mount with respect to another object in 90 degrees increments. The first mount is coupled with the first ferromagnetic coupling element and the first mechanical coupling element.
