The weld transfers all the torsional force! I recommend you throw away that round tube garbage, grind some flats onto the yoke and stick it in a piece of square tubing. Toss a little weld at it (which now, with this inherently better design, has the sole purpose of holding the two pieces together...torsional force is transferred by the square interface!) and you're good to go! Advice and technical assessment free of charge...you're welcome! :D
