<p>The module (1) has a base plate with two lateral surfaces, a rear side (11) and a front side (4). A slot is held in one of the lateral surfaces, and a feather key (20) is attached to the other lateral surface. Two receiving holes (14, 15) are provided in the base plate, where axes of the receiving holes stay perpendicular to a plane, which is defined by the front side. A cross hole (31) passes through the base plate centrally between the two receiving holes and serves as a bearing for a tensioning medium. An independent claim is also included for coupling halfs from two modules.</p> |
