2.0 What is the difference between a Lever (Turnable) and a Valve (Symmetric Turnable)?

The Valve (Symmetric Turnable) is always used in situations where I need to rotate something with both hands simultaneously. A memorable example of this would be a large safe wheel that must be turned using both hands.

The Lever Turnable, on the other hand, is used whenever I want to simulate rotating objects around a fixed point. These can be objects such as levers of any kind. Valves, handwheels, and similar elements can also be simulated in this way. The Lever Turnable is always operated with one hand.

The Lever Turnable also includes several features that define how the rotation should occur and how the actor can be solved using logic-based behavior.
