Helical pile assembly with top plate

A helical pile assembly, comprising:

• a plate;
• a rod extending from the plate, wherein the rod comprises threads;
• a piling configured to be disposed in a ground and support a load;
• a nose coupled to an end of the piling;
• a helix coupled to the nose and extending outward therefrom;
• a connection device positioned around the rod and configured to transmit torque to the piling, wherein the connection device comprises threads that are configured to engage the threads on the rod;
• a lock member received around the rod and movable axially along the rod, with respect to the plate, by rotating the rod with respect to the lock member, wherein the plate is prevented from moving closer to the connection device when the lock member contacts the connection device;
• and
• an adapter positioned at least partially around the connection device and the piling, wherein the connection device comprises a plurality of planar outer surfaces that contact inner surfaces of the adapter.
