Systems, vehicles, and assemblies that include a prime mover, a transmission, and a coupler. The coupler couples the prime mover and the transmission. A preferred embodiment includes a system for forming a rigid body that includes a rotational prime mover and a transmission assembly. The transmission assembly transmits at least a portion of the rotational energy from the prime mover to a driven member at a frequency. The system includes a first and a second bridging member. Coupling the first bridging member to the second bridging member forms a symmetric bridge or coupler. The symmetric bridge is symmetric about a first plane of symmetry. Furthermore, coupling a first portion of the bridge to the rotational prime mover and coupling a second portion of the bridge to the transmission assembly forms the rigid body. The rigid body further includes the bridge.

Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.
