What components make up a flanged/muffed coupling?

A flanged or muffed coupling is a mechanical component used to connect two shafts while allowing for some misalignment and flexibility during operation. The correct choice mentions bolts and keyways, which are indeed essential parts of this coupling type.

The bolts serve to secure the two flanged ends of the coupling together, ensuring a tight and stable connection between the shafts. Keyways, on the other hand, are slots cut into both the shaft and the coupling that allow for a key—a small metal piece—to fit in and prevent the shafts from slipping relative to one another during operation. This design maintains the alignment and transfers torque effectively between the connected shafts.

Understanding the structure of a flanged or muffed coupling helps grasp how mechanical connections maintain functionality, especially in scenarios where components must be easily assembled and disassembled for maintenance. Other listed options do not provide the necessary components for this type of coupling, making them less relevant in this context.
