The coupling sits between the motor shaft and the pump shaft. When the motor spins, the coupling transfers that spinning motion to the pump. The “spider” is the soft rubber piece in the middle . It looks like a little star or spider. That soft piece absorbs shocks and vibrations. It protects both the motor and the pump from damage.
