I have a CL50 Robot Coupe. The master shaft pin that slides in the shaft broke off on either side leaving the rest of the pin stuck in the shaft. I tried hammering it out with screw and hammer but looks like its seized inside the shaft. Any input on best way to get this out to install new pin?

A screw? REALLY?! A SCREW is NOT a proper pin punch tool. DON’T DO THAT!
Get you a quality set of pin punches. Use the largest size punch that will j-u-s-t fit inside the hole your broken pin is in. Cradle the shaft on a metal base such as a close brass nipple with the hole that the pin is in centered over then opening of the nipple. The nipple itself should be set upon a THICK metal table or concrete (I’ve used parking curbs on occasion).
All this is so you have a solid, immovable platform, a place for the pin to push through into…and an anvil under the shaft that won’t harm the shaft.
THEN, use a decent sledge hammer to pound away at the pin punch.
Don’t forget to wear some safety goggles while doing all of this.
Here are tools similar to what I own to accomplish such a task:
