No not really, it's to prevent the crank shaft from snapping in a over torque situation. It allows a little cushion to lessen the sudden power transfer. It also serves as a vibration isolator, Motor vibration through a solid shaft would shake a gear box to death. It also creates a flexible joint where the motor can flex and rock while the gear box is bolted solid. These connectors are commonly used when connecting a fluid transfer pump or a stand alone transmission to a motor.
