The Brit cruised to gold in the Olympic Stadium a day after Weir rode to victory in the T54 5000m final.
"Gold was the only thing I wanted," The Telegraph quotes Bushell as saying. "I know I had to work for it, it's been a long, hard four years.
"I watched Dave Weir and as he crossed the line I was bouncing off the walls in my room. I didn't know what to do. He's been a massive influence - just as a teammate, he's been there for me.
"He was there for me in Beijing as well, even with all the stuff he had to deal with as well. He's a fantastic guy, a great role model to look up to."
Meanwhile, Weir will take to the track this evening for the men's T54 1500m final.
