A connection device connects a driving device and a feeding device and is for use in a scale or combination scale. A connection element has at least one magnet. A receiving device, which is located within the feeding device, includes at least one iron core. The receiving device includes a protrusion, where the receiving device meshes with the connection element in the mounted state for a simple, interlocking, and backlash-free self-centering connection.

A system for assembly of components, including a vibrating device wherein the components are placed in bulk, which is provided with first and second compartments connected together at their ends by first and second passage zones to form a closed circuit wherein the components can flow, and an articulated gripping arm provided to distribute the components to an automatic assembly installation, the vibrating device including first and second planes inclined in opposite directions included, respectively, in the first and second compartments, the components being able to progress along the first and second inclined planes towards a supply platform on which at least one component can be arranged in advance of its seizure by the articulated gripping arm, the supply platform being located in the second compartment at an exit of the second inclined plane.
