1. A spring compression tool used to marry a first assembly to a second assembly via a spring, the spring compression tool comprising:
a frame defining an X/Y plane;
a spring clamping unit movably attached to the frame, the spring clamping unit having a clamp with a clamp head, the clamp head movable in a Z-direction relative to the frame;
a moveable frame moveably connected to the frame, the moveable frame movable in the Z-direction relative to the frame;
one or more supports mounted on the moveable frame and configured to hold the first assembly; and
one or more control systems operable to compress a spring held in the clamp head and move the clamp head in the Z-direction to adjust a height of the spring held within the spring clamping unit in real-time fashion to achieve a desired spring height during marriage of the first assembly to the second assembly.
