A magnetic coupling for a stirrer drive in a high pressure autoclave in which the magnet shaft is in the form of a sleeve-like bush fixed on the end of the stirrer shaft. A portion of the magnet shaft serves as a carrier of segmented permanent magnets on the outside. An inner coupling part, including the magnet shaft, is covered by a hood and the outer coupling part comprises a bell equipped with permanent magnets on the inside. The bell covers the hood.
