Ever seen a flexible coupling fail in a way that tells a story?

Take this example: a coupling element where the central hole has deformed into a square shape. At first glance, it looks unusual, almost like a manufacturing defect. But in reality, it’s a clear signature of overload in action.

Here’s what’s happening beneath the surface:
