Their absolutely is. A hardware wallet can take unsigned transactions and sign them internally, and output a signed transaction. Your private key never leaves the hardware wallet.
Compare this to signing a transaction with a private key on a computer. Your computer can have spyware that can snoop on the key and steal your coins.
The hardware wallet has a burned ROM with a firmware that is signed and verified every time you use it.
