Abstract
A torque limiter can include a housing and a shaft. The housing can include a housing magnet enclosed within the housing. The shaft can be at least partially surrounded by the housing and can be rotatable within the housing. The shaft can include a shaft magnet integrated with the shaft to magnetically couple with the housing magnet to transmit a torque between the housing and the shaft and configured to uncouple from the housing magnet allowing the shaft to rotate within the housing when a threshold torque is reached.
