I added your solution to the script. It works, thanks.

    # Add driver from 'selected' object to target 'active' object.
    # Target values are shape_key values
    # 
    # ShapeKeys must be named after Object for the script to work:
    #
    #      selected Object     = Cube
    #      selected Shape Keys = Cube_abcd
    #
    #      active Object       = Sphere
    #      active Shape Keys   = Sphere_abcd
    #      
    # 1. Select all object candidates to receive a driver.
    # 2. Select 'active' object as driver target. 
    # 3. Run script.
