<p>A system for transmitting motion between means separated by a partition wall includes power means (3), operating a first magnetic disc (6a), which faces said partition wall (7). A second magnetic disc (6b), situated opposite to the first magnetic disc (6a) and separated therefrom by the partition wall (7), is connected to at least one working member (30) and defines a magnetic coupling with the first magnetic disc (6a), to allow the transmission of the motion from the power means (3) to the working means (30). The second magnetic disc (6b) and working means (30) are situated in a controlled atmosphere environment, defined by a chamber, separated from outside by means, to which the partition wall (7) belongs.
