1. A coupling assembly, comprising:
an upper adapter having an upper adapter body that provides a latching collet and a torque collet axially spaced from the latching collet, the torque collet including a plurality of axially-extending torque members and a corresponding torque lug provided on each axially-extending torque member; and a lower adapter having a lower adapter body configured to receive the upper adapter body and providing a series of latch mating threads defined on an inner surface of the lower adapter body for matingly engaging the latching collet, the lower adapter body further providing a torque collet profile that defines a plurality of longitudinal slots for receiving the torque lugs therein, wherein, when the upper adapter is received within the lower adapter, the upper adapter is able to apply compression and tension loads to the lower adapter, and wherein, when the torque lugs are received into the plurality of longitudinal slots, the upper adapter is able to apply torque to the lower adapter in at least one angular direction.
