If you have an option to DO or GET DONE, and you can stand up and say I DID when it goes wrong and say WE DID when it goes right, you have the authority.
If you just do what is said or required, then you have the responsibility.
If you write a cheque .. you have responsibility
If you sign a cheque .. you have authority
If you test and prepare an inspection report .. you have responsibility
If you approve or pass that inspection report .. you have authority
If you prepare a PO .. you have responsibility
If you signoff that PO .. you have authority
If you draft an engineering drawing .. you have responsibility
If you release that drawing for procurement .. you have authority

You can have responsibility without an authority
When you have authority, you have responsibility too
