Looks like you have an old Roto operator. These generally use a 5/16" hex to attach the handle to the operator base, though you may want to confirm. You'd have to remove the broken bit your arrow is pointing to in each picture. That broken bit is what remains of the old handle.

The first part to come to mind is our 39-224, which is designed to work with modern Roto operators with that 5/16" hex spline. The only thing is, this is a female handle for a male operator. I'm not sure if that pattern matches what you have, or if you have a male handle with a female operator. That is a possibility, but removing the old handle remnant will confirm easily enough.
