Fail-safe Actuators: When Failure Is Not an Option
Actuators are a small part relative to the overall systems they live in. Many of these devices weigh in at only ten or twenty pounds. But they are a small component that plays a crucial role: When it's time for a valve or damper to close, for a flow to stop, or for a system to shut down

Torque Switch Application Notes
The primary function of a torque switch is to sense a high torque situation in a valve and shut down the actuator. This causes a halt to the process, but any situation that would trip a torque switch would likely halt it anyway, foul up the process, and also damage the equipment.
